Дослідження електротехнічного комплексу вантажного електромобіля

Abstract

As a result of the performance of the master's qualification work, studies were carried out of the electrical complex of a cargo electric vehicle. The development of the traction electric drive is carried out. Preliminary calculation of the electric motor power. Based on the technical and economic indicators, the electric drive system was chosen, the electric motor was calculated and selected, it was checked for its heating, overload capacity and starting conditions. The control system is proposed and the elements of the converter unit are selected. A block diagram is proposed for reducing the DC current for recuperation and the functional circuits of the frequency converter and direct torque control with the inclusion table and the speed sensor. The characteristics in statistical and dynamic modes are investigated. Modeling in the Matlab PPP has been carried out for SAEP, a check for durability has been carried out.
